Microscopic description of the surface dipole plasmon in large Na_N clusters (950 < N < 12050)

TL;DR

This paper presents detailed microscopic calculations of the surface dipole plasmon in large sodium clusters, exploring how plasmon properties evolve with cluster size in the range of 950 to 12050 atoms.

Contribution

It provides the first comprehensive microscopic analysis of plasmon behavior in very large sodium clusters across a wide size range.

Findings

Analysis of plasmon width and position as a function of cluster size

Identification of asymptotic behavior of plasmon properties

First microscopic calculations for clusters of this size range

Abstract

Fully microscopic RPA/LDA calculations of the dipole plasmon for very large neutral and charged sodium clusters, Na_N^Z+, in the size range 950 < N < 12050 are presented for the first time. 60 different sizes are considered altogether, which allows for an in-depth investigation of the asymptotic behavior of both the width and the position of the plasmon.
